Concerts are probably only a small factor in the plans. I think stuff like boxing and MMA could prove to be huge draws in a building like that in Vegas.

They also want to try to host an NFL game (or two) eventually, it almost sounds like.

And some sports expos, fairs, and even an awards show...apparently

...think if they get this thing off the city might also eventually try to make a pass at the PAC-12 as a championship game site? (not that a group of major universities would be likely to take them up on it)
